I had repeated d80 codes with my LG dryer that I got in Dec 2020. When I installed it I made sure to totally clean the 4″ metal vent pipe that went up through my wall and vented on my roof. I went on the roof and made sure the vent was clean with nothing blocking it. Did some research and the vent cap on the roof was really too small and also had been installed incorrectly back in 1996 when my house was built. I purchased a new larger dryer vent cap for the roof…had it installed and problem solved! Clothes dry much faster and never get the d80 code anymore. I purchased a DryerJack vent cap.
We too almost always get the D80, sometimes the D90 and the 4 bars on the flowsense. Sometimes it still runs the full dryer cycle fine, sometimes I have to put it on multiple times. Our filters are clean, our vents work fine. And oddly we’ve noticed if we switch to speed dry function then all flowsense and D80 disappear. Does this mean it’s a sensor problem? Thanks!
I get the d80 code. It started almost from the get go. I checked the vent and it’s clean. My clothes come out dry. My dryer is less than 2 months old. My venting hose is only a couple of feet. Any suggestions.
DLe 2301r LG dryer says to check filter. I have, and also disconnected vent hose and cleared dryer. It still says to check filter.
